BACKGROUND Fat embolization (FE) is an often overlooked and poorly understood complication of skeletal trauma and some orthopedic procedures. Fat embolism can lead to major pulmonary damage associated with fat embolism syndrome (FES). METHODS A model of FE in unanesthetized rats, using intravenous injection of the neutral fat triolein, was used to study(More)
The pathophysiology of Fat Embolism Syndrome (FES) is poorly understood and subject to some controversy. Evaluation of the evolution of histological changes in the lungs of patients with FES is impractical. The current theories of FES were established through acute clinical observations and acute animal experiments, but sequential changes in the histology(More)
INTRODUCTION Infiltrating myoepithelial carcinoma remains a rarely encountered lesion of the breast. The few cases that have surfaced firmly document the histopathology of this tumor, but its cytologic characteristics seemingly have been described in only one other report. CASE PRESENTATION Here we present the cytologic findings from a case of(More)
BACKGROUND Fetal growth restriction (FGR) is associated with adverse outcomes extending from fetal to adult life, and thus, constitutes a major health care challenge. Fetuses with progressive growth restriction show increasing impedance in the umbilical artery flow, which may become absent during end-diastole. Absent end-diastolic flow (AEDF) is associated(More)
We present the case of a 46 year old woman with a giant, 23-centimeter, atypical carcinoid of the liver. A primary site for this neoplasm could not be identified despite multiple radiographic imaging studies, including a somatostatin scan, and a thorough inspection of the bowel during surgical resection of the lesion. Histologically, the tumor displayed(More)
BACKGROUND Women with low grade squamous intraepithelial lesions (LSIL) at cervical cancer screening are currently referred for further diagnostic work up despite 80% having no precancerous lesion. The primary purpose of this study is to measure the test characteristics of 3q26 chromosome gain (3q26 gain) as a host marker of carcinogenesis in women with(More)
BACKGROUND Deep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic nevus. It often goes unrecognized due to its relative rarity. CASE PRESENTATION Here we report a case of(More)
BACKGROUND Fat embolism (FE) after trauma and some orthopedic procedures is known to cause acute lung injury, including acute respiratory distress syndrome. However, its potential long-term effects on the lung are unknown. A previous study using a rat model of FE found significant histopathologic changes in the lungs after intravenous injection of triolein(More)
Aggressive digital papillary adenocarcinoma (ADPA) is a rare tumor that is considered to arise from eccrine sweat glands of the skin. It occurs predominantly in men with a mean age in the sixth decade. It shows a strong tendency for local recurrence and has the potential to metastasize to distant sites. Prompt diagnosis and regular follow-up are important(More)
